Abstract
The utility model discloses an energy-efficient copper aluminum transition connection terminal which includes a clamping groove seat, a terminal row, two clamps and two pairs of bolt; the center of the clamping groove seat is provided with a concave groove; a plurality of ribs are uniformly distributed in the groove; the clamping groove seat at two sides of the groove is provided with two pairs of screw holes; one clamp corresponds to one pair of bolt and one pair of screw hole; each clamp through the corresponding one pair of bolt and the corresponding one pair of screw hole is fixedly screwed with the clamping groove seat; and the terminal row is fixedly connected with the clamping groove seat. The energy-efficient copper aluminum transition connection terminal can be electrically connected with the copper or aluminum terminal; the contact resistance is small, the flow capacity is high, so that the magnetic hysteresis loss can be effectively reduced; and the friction between the wire and terminal can also be increased, so that the wire is not easy to fall off.
Description
Technical field
The utility model relates to high-voltage electrical apparatus field, relates in particular to a kind of copper-aluminum transition connecting terminal.
Background technology
Power equipment (as circuit breaker, isolating switch etc.) adopts copper terminal block to external wiring terminal, and civilian transmission pressure is for cost consideration, adopt more and more aluminum cable, electrical connection between unlike material, is easy at tie point place because of electric accidents such as the disconnected phase of generating heat, supply line appears in burn into disconnection, short circuit, power failures.Along with the high speed development of national grid, the extension of electric line and the increase of power equipment, copper al wiring problem has become to solve a large problem of power supply safety.
For fear of above-mentioned accident, adopt at present conventionally copper-aluminium transition binding clip, make between the conductor of identical material overlap joint mutually, this binding clip one end is copper material, and the other end is generally tubulose aluminium, and main employing welded at section part.Welding procedure mainly contains flash welding, friction welding (FW) etc., is substantially to make section reach thermoplasticity state, and then rapid upset, completes welding.This technique is often restive, because the fusing point of aluminum metal is lower, and very easily oxidation, and have obvious weld seam, and the phenomenon of solder side fracture occurs now and then, and the fusion rate of part welding point weld seam only has 17%.In addition, the copper-aluminium transition wire clip of soldering, explosive welding (EW) and copper aluminium composite sheet pattern is the surface that layer of copper is covered in aluminum substrate, though without obvious weld seam, weld the bad copper aluminium that easily causes and peel off.
Summary of the invention
The purpose of this utility model is to provide a kind of copper-aluminum transition connecting terminal, can realize electrical connection with copper or aluminium terminal, and contact resistance is little, through-current capability is strong, can effectively reduce magnetic hysteresis loss, can increase the frictional force between wire and terminal, make wire difficult drop-off simultaneously.
The technical scheme that realizes above-mentioned purpose is:
A kind of energy-saving copper-aluminum transition connecting terminal, comprises draw-in groove seat, terminal board, two clips and two pairs of bolts, wherein:
Described draw-in groove seat central authorities are arranged with a groove, are evenly equipped with some fins in this groove; On the described draw-in groove seat of described groove both sides, have two pairs of screws;
The corresponding pair of bolts of clip and a pair of screw, each clip is consolidated by each self-corresponding pair of bolts and a pair of screw and described draw-in groove seat spiral shell;
Described terminal board and described draw-in groove seat are affixed.
In above-mentioned energy-saving copper-aluminum transition connecting terminal, described terminal board and described draw-in groove seat are one-body molded.
In above-mentioned energy-saving copper-aluminum transition connecting terminal, down, the both ends horizontal of described clip also all has the through hole passing for described bolt for the concavo-convex formation certain radian in the middle part of described clip and concave surface.
In above-mentioned energy-saving copper-aluminum transition connecting terminal, described draw-in groove seat, terminal board and two clips are albronze.
The beneficial effects of the utility model are: a kind of copper-aluminum transition connecting terminal that can coordinate with copper/aluminum connecting terminal, exempt from welding, be easy to moulding of the utility model development, directly apply on power equipment, both saved electric power purchase cost, improve again power transmission efficiency, contact resistance is little, through-current capability is strong, can effectively reduce magnetic hysteresis loss.Meanwhile, play by groove is set the effect that makes enlarge active surface and frictional force between wire and terminal, make wire difficult drop-off.
Brief description of the drawings
Fig. 1 is the structural representation of copper-aluminum transition connecting terminal of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, copper-aluminum transition connecting terminal of the present utility model, comprises draw-in groove seat 1, two clips 2, terminal board 3 and two pairs of bolts 4, wherein:
The central fovea of draw-in groove seat 1 is provided with the groove 11 of anti-slip and locking strand, is laterally evenly equipped with the fin of some arcs in groove 11, is connected with wire, increases the frictional force between wire and terminal, makes wire difficult drop-off.On the draw-in groove seat 1 of groove 11 both sides, have two pairs of screws 12;
Corresponding pair of bolts 4 of clip 2 and a pair of screw 12, each clip 2 is solid with draw-in groove seat 1 spiral shell by each self-corresponding pair of bolts 4 and a pair of screw 12, particularly, clip 2 is the form of concavo-convex, the both ends horizontal in middle part, that is: the clip 2 concavo-convex formation certain radian in middle part, and concave surface is faced with groove 11 down, clip 2 has the through hole 21 passing for bolt 4 separately.
Terminal board 3 is one-body molded with draw-in groove seat 1, and touches mutually with groove 11 1 outlets; Terminal board 3 can be directly as the outlet terminal load facility of electric equipment, the standard of also can making connect row as with the use of electrical apparatus interstar connection end transition.
Draw-in groove seat 1, terminal board 3 and two clips 2 are albronze.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
